Abstract

The Gunungsewu karst area is not only known for its unique landscape but also its recurring drought events. To meet the water supply, the local population utilizes several water potentials, namely doline pond, spring, and underground river. This study was designed to analyze the hydrogeological conditions of Mbangsri Cave, following its accidental discovery by the community at the end of 2018. The hydrogeological analysis was conducted by geological surveys, which consisted of rocks collection and structural measurements, cave mapping, and recharge area delineation based on remote sensing images acquired by unmanned aerial vehicles. The results showed that Mbangsri Cave, in the hydrogeological perspective, had low water resources potential. It is believed to be the result of (1) relatively small catchment area, (2) a fault in the southern part of Mbangsri Cave, creating a small groundwater basin, and (3) the thin epikarst layer, limiting the water storage.

Abstract

Sungai Lamandau merupakan salah satu sungai utama yang mengalir melewati dua kabupaten di Provinsi Kalimantan Tengah yakni Kabupaten Lamandau dan Kabupaten Kotawaringin Barat. Di Kabupaten Lamandau, sungai ini mengalir melewati Nanga Bulik sebagai pusat Kabupaten Lamandau. Perkembangan daerah, baik Kabupaten Lamandau dengan Nanga Bulik memberikan tekanan kepada Sungai Lamandau dimana terjadi pencemaran yang pada akhirnya menurunkan nilai kualitas air Sungai Lamandau. Padahal, sungai ini menjadi salah satu bagian hidup masyarakat yang memanfaatkan airnya serta mata pencaharian dan sepanjang sejarah mengiringi masyarakat dayak tempatan untuk berkembang. Penelitian ini bertujuan untuk mengkaji dampak perkembangan terhadap kondisi Sungai Lamandau dan diharapkan menajdi masukan untuk penetapan kelas sungai dan peraturan yang mengaturnya. Untuk mencapai tujuan tersebut, penelitian ini menggunakan metode kuantitatif untuk menganilisis kualitas air Sungai Lamandau dan kualitatif untuk mengelaborasi hasil perhitungan tersebut. Sistem Informasi Geografis juga digunakan untuk mendukung analisis dan penjabaran. Berdasarkan hasil sampel dan analisis, ditemukan parameter sungai yang perlu menjadi perhatian yakni pH, DO, Fecal Coliform, dan Deterjen. Faktor yang mengontrol parameter tersebut berasal dari faktor alami dan faktor aktivitas manusia berupa pemukiman sehingga berperan dalam penambahan Fecal Coliform dan Deterjen. Indeks Pencemaran

Abstract

Limestone mining is a problem in the karst area because it causes environmental degradation, social change from the agrarian to industrial, and conflicts among stakeholders. Therefore, the limestone mining is not only identified as the environmental damage problems but also environmental management problems. The article aimed to explain an overview of the mining conflicts in the karst region. On the other hand, this study also provided a new approach in understanding the conflicts of mining. The study was conducted using qualitative descriptive analysis. Analyses were performed using stakeholder mapping and potential conflicts between stakeholders. The mapping results were contextualized using field and capital approach of Pierre Bourdieu theory. The approach used to understand the direction of conflicts and capital contestation of each author. The capital analysis showed that the government, namely the Energy and Mineral Resources in various levels of bureaucracy has the dominant capital in the arena of limestone mining in Ponjong District because it has a complete capital and outperforms of the other actors. It concludes that the differences types of capital affect the actors to take the position in an arena and each actor who has a robust capital sought to accumulate the capital to attain the main capital.

Abstract

Gunung Sewu’s karstic aquifer characteristic of fracture-fissure water conduit leads to pollution problem in the water resources. One main source of water used is the Baron Spring. This study aims to analyze the water quality of the Baron Spring toward the land use in the catchment area and provide recommendations for spatial planning and water management in certain area. This research used spatial analysis of GIS and water quality was analyzed by Pollution Index. The results showed that the Baron Spring was in a mild contaminated state with amount of TSS was 97,1 mg/L, bicarbonate 96 mg/L, total coliform 210 MPN/100ml, and total oil and fat 2 mg/L which have exceeded the water source quality standards. Those results are related with the land use in the catchment area where settlement is dense in the upstream, also because of the distribution of settlement and sinkhole in the middle-part of catchment. In coping with the contamination and pollution several strategies are urged to be designed and implemented. Strategies comprised by two approaches, socio-cultural and spatial approach. Each of the approaches is linked and should not be separated. Management of catchment including stakeholder involvement and spatial planning are essential to be considered.

Abstract

Karst area has a crucial role in providing water resource. However, due to the intrisic characteristic, water resource in the karst area is highly susceptible to the pollution and relatively hard to manage because the complexity of the aquifer. Karst of Gunung Sewu as one of the main karst area in Indonesia has abundant water resource inside the cave but the utilization is very limited due to the technical constraint to lift the water and distribute it. One the main water resources in Karst of Gunung Sewu is the Pulejajar Underground River at Jepitu Village. As one of the main water resource, a management to maintain its water quality is very important. We examine the water quality of the Pulejajar Underground River and study the factors that affect it. We employ water sampling using purposive sampling in 4 locations and analyze it using Pollution Index (PI) calculation and view the spatial context of the underground river using GIS tool. As the result the PI for the sampling location consists of lighlty polluted in the water intake and the small junction of the Pulejajar Underground River and heavily polluted in the big junction and the Puring Spring. The pollution comes from the Calcium and E. Coli parameter which originates from the dissolution of limestone and the feces of the livestock because the poor filtration at the karst area. The management strategies suppose to comply with the SDGs number 6 as the main framework dan must cover the both side of human side and the nature side including land cover management, water accessibility, and conservation of the catchment area.
